The fee to climb Mount Rainier has gone from $30 to $43 this year. Mount Rainier National Park announced the increase Tuesday after a public process.

The increased revenue to the park will help maintain safety, keep the upper mountain clean and to pay training fees and salaries for climbing rangers.

The fee for ages 24 and younger will remain $30. They make up less than 10 percent of the 10,000 climbers who attempt the 14,411-foot every year. The mountain is the highest in Washington and the Cascades.
